> When I configure the yarn.scheduler.fair.locality.threshold.node and yarn.scheduler.fair.locality.threshold.rack
to open this function, I have no detail info of assigning container's locality. And it's important
because it will lead some delay scheduling and will have an influence on my cluster. If I
know these info, I can adjust param in cluster.
